Maybe 2 in a night (not counting thou dropping in and out of LDs). I used to thou have very long LDs, over 1 hr (maybe up to 90mins).

I dont think the number in one night is very important but how good the LDs are themselves which is more important. I'll take quality over quantity any day.

edit.. way back I used to have far more. I went throu a stage where all my dreams where going lucid (I can have up to 8 dreams per night), this thou was a nightmarish situation for me being "awake" when I as asleep the whole time, as I felt like my thinking mind was getting any proper rest at all. I quit doing LD in the past for a long due to my waking mind loosing its ability to shut off (it took a while before the LD state would switch off and I learnt how to not aware sleep again). Many of those lucids were like 3rd party ones where I was like an observer watching the dream.

1 per night . But a long time ago I had 3 nights in a row of getting a lucid dream. I knew exactly what I did those nights but for some reason the magic died when i had 2 weeks of no LDs when doing the exact same thing
